40d:Gem

Small clusters of rough gems can be found strewn throughout the mountain. Cut gems can be used to encrust furniture, crafts, weapons, armor and ammunition, to create windows and as a source material for legendary artifacts. In addition, raw rock crystals are required to make crystal glass goods. Large gems are a byproduct of cutting and can not be processed further. They have a high base value for an item(10x) and can easily reach hundreds, even thousands depending on the gem. Artifact large gems made from precious jewels will go for around 50,000.

Value

Gems have base value of 3 in rough form, which is multiplied by the appropriate value modifier from the table below. They gain value after they are cut in a jeweler's workshop. Cut gems have a base value of 5. Items can be decorated (encrusted) with cut gems; all such decorations have a value of 10 times the gem type's value multiplier. See Gem cutting and Gem setting. Large gems have a base value of 10.

Varieties

Gems come in many varieties, with their own color and value multipliers:

Unlike other gems, diamonds can ignite if they come into contact with magma.

Rare Gems

Faint yellow diamonds only appear in kimberlite (which itself only appears in gabbro layers) and sapphires and rubies only appear in bauxite (which occurs in any sedimentary layers). Colored diamonds only occur in pre-existing clusters of faint yellow diamonds. Star sapphires and rubies only occur within clusters of their peers.

Glass

Like working metal, making glass requires fuel, either coke or charcoal at a normal glass furnace, or magma at a magma glass furnace.

Raw gems are only one of the many things your glassmakers can make from glass. It's possible to make most furniture from glass, including Tables and Doors. Glass windows can also be made at a glass furnace as an alternative to making windows from gems. And trap components, such as spiked balls or giant axe blades, can be made from glass. Glass trap components have the same weapon damage as wood or silver (50%). They're easier to make than metal weapons because you don't need ore.

Outside of Metal and Wood, Glass is the only readily available material to create Cages (called terrariums) out of, as well. And Glass is the only material available for making aquariums.
